Sweet! Then use the CR. In the most common kinds of steel in the US, CR is about 20% harder than it's HR counterpart. Hardness is usually equated to strength when discussing metals. Just remeber, the harder the metal is, the more brittle it becomes. You are more likely to crack the CR and more likely to bend the HR.

Neither of the above is a factor that is going to matter in your application. What are you using? 3/16?

 

I have 3/8" cr for lower frame side brackets and 3/8" hr for axle side upper laying around. 3 link with panhard.

 

Lol. That will be more than sufficient. Have you seen the stock ones?

 

Of course but stock crap gets ripped off mall crawling. I wheel pretty difficult trails on 35s and steel beadlocks. And considering I'll have one upper control arm, I need to be beef there.

 

Sweet. Thanks for the tech Ian



the D30 is so light that it will be a challenge to rip off heavy duty mounts. all the strength will come from the design and the weld. I think you're overthinking this, but if you're really worried about it and you have access to steel you can box it all in with a truss. or at least add gussets

 

Planning on at least one gusset 2 if I can fit them. I'm not going to mess with trussing it. If it gets to the point where I need to truss on a Dana 30 then I'll be upgrading anyway.
